Why the figure-8 beats older methods
Williamson turn (180° heading reversal): designed for ships, requires precise rudder timing and a long, predictable wake. Loses sight of the victim during the turn.
Quick-stop / figure-8: keeps the victim in sight at all times, ends with the boat stopped into the wind alongside the victim, requires no exact heading or speed.
The figure-8 is what every modern offshore racing rule (US Sailing Safety at Sea, World Sailing OSR) teaches because it's recoverable from any point of sail and any conditions.
The 90-second sequence
Second 0–5: Anyone who sees the person go over yells 'MAN OVERBOARD' and points. The pointer becomes the spotter and points continuously, never breaking eye contact.
Second 5–10: Helm presses the MOB button on the chartplotter (captures GPS position) and throws a Lifesling, Type IV cushion, or any floating object overboard immediately — a trail of debris helps relocate the position even if the spotter loses sight.
Second 10–60: Helm turns the boat onto a beam reach away from the victim, sails or motors one boat length, then tacks or turns through the wind onto a close reach back toward the victim.
Second 60–90: Approach into the wind, stopping 1–2 boat lengths upwind. The boat drifts down to the victim while the crew rigs the Lifesling or boarding ladder.
Equipment that makes the difference
Lifesling: a horseshoe-shaped buoy on 150 ft of floating line attached to the boat. Tow it past the victim, who pulls it under their arms; you then haul them to the boat. Recovery is reliable even with a single-handed sailor.
MOB button on the chartplotter: marks position with one press. Use it for GPS coordinates to give USCG if you lose visual contact.
Personal AIS beacon or PLB clipped to each PFD: transmits position in case of separation. Increasingly standard offshore.
Boarding ladder or block-and-tackle hoist: getting an unconscious or hypothermic adult out of the water and into the boat is the part of the drill that goes wrong most often. Practice it with a full-size dummy in calm water.
Hypothermia and cold-shock realities
In water below 60°F, cold shock causes involuntary gasping in the first minute — the leading drowning mechanism in MOB events. Wear a PFD that supports the head face-up.
Functional swimming time in 50°F water is 10–20 minutes; consciousness window is around 30 minutes. The figure-8 maneuver typically completes in 90 seconds; getting the victim aboard takes another 2–10 minutes depending on technique. Practice that part.
After recovery, treat for hypothermia: dry clothes, blankets, calorie-dense food, warm (not hot) drinks if conscious. Don't massage extremities — drives cold blood to the core and can trigger cardiac arrhythmia.
Drill schedule
Once per season with every regular crew member. Use a fender on a line as the 'victim.' Practice in real wind, not flat calm.
Once per year with a real human in the water (in safe conditions, with safety boat) — only this teaches you how slow and how heavy the recovery actually is.
Brief every new guest in the first 10 minutes aboard: where the MOB button is, where the Lifesling lives, what to do if they see someone go over.
Step by step
- 1
Shout 'Man overboard'
Designate a spotter who points at the victim and never breaks eye contact. The spotter only spots — no other tasks.
- 2
Hit MOB on the chartplotter
Captures GPS position. Throw a Lifesling, Type IV cushion, or any floating object overboard immediately.
- 3
Turn to a beam reach
Sail or motor one boat length on a beam reach away from the victim. Time to think, set up the recovery.
- 4
Tack or turn through the wind
Bring the boat onto a close reach heading back toward the MOB. Aim slightly downwind of the victim.
- 5
Stop upwind
Approach so the boat stops 1–2 lengths upwind of the victim, drifting down. Sails luffing, engine out of gear if motoring.
- 6
Recover with Lifesling
Drag the Lifesling around the victim, then haul aboard with halyard, mainsheet block-and-tackle, or boarding ladder. Mind the prop if engine is on.
- 7
Treat for hypothermia
Dry clothes, blankets, calorie-dense food, monitor for cold-shock arrhythmia. Call USCG on Ch 16 if any concern.
Frequently asked
Yes if available — but kill the prop before the victim is anywhere near the boat. A turning prop on a person in the water is a death sentence.
